Doctors often use tongue depressors when peering in a patient’s mouth and throat. But what if that flat wooden spatula could actively evaluate the patient’s health? That’s the premise of an ecofriendly disposable sensor, reported in ACS’ Analytical Chemistry, that can check levels of glucose and other biomarkers in saliva. Researchers say the easy-to-produce device could someday help doctors assess a range of conditions.
Wood is a renewable, biodegradable, natural material that is widely available at low cost, which makes it attractive for researchers who design electronics and sensors. However, this is challenging because the material isn’t good ...
